KeyHelp offers several ways to create a certificate. Select the desired method from the drop-down box.


Generate CSR / Self-signed Certificate

What should be created?

Certificate signing request (CSR)
Select this if you want to create a CSR that you can forward to a certificate authority to receive an official certificate.

Self-signed certificate
Select this if you want the server to generate a certificate of its own. You can also use this to secure your websites. However, corresponding client programs (web browsers, email clients) issue a warning.

Select the desired key length. Currently, key lengths of 2048 bits are generally considered sufficiently secure.


Select the country.

Organization / company

If you want to order a certificate, which includes several domains, the additional domain names will be added later by the issuer. Please enter only one domain name here.

Upload an existing certificate

Here you can upload an existing certificate.

You can upload the corresponding certificate files directly. Click on the button "Browse / Select file" under "Upload certificate files" and select the corresponding file for upload.
Common file extensions are:

".key" for the private key
".crt" for the certificate
"-ca.crt" for the root/intermediate certificate of the certificate issuer.

Or copy the text of the certificate components into the input fields under "Upload certificate as text".
You can recognize the correct certificate component by the header/footer line:

"-----BEGIN PRIVATE KEY-----" / "-----END PRIVATE KEY-----" for the private key
"-----BEGIN CERTIFICATE-----" / "-----END CERTIFICATE-----" for the certificate or the root/intermediate certificate of the certificate issuer.



Finally, click on the button to save the settings:
